I'm swapping out my old drive with a new sold state one. First step is to clone the drive, so I've put my Samsung 500GB SSD in a X-Media USB HDD enclosure. After I plug in drive via USB and the LED lights up, I only get this far: Get error message: “The disk you inserted was not readable by this computer" I click “Initialize"Disk Utilities pops up, asks to select disk I chose the external HD icon, named “disk2"All actions under First Aid, Erase, Partition, etc. are greyed out I ran Disk Utilities from recovery mode and was able to get it to partition, but it error'd out right at the end. Any suggestions?
